PURPOSE:To control axes along the tool course according with a preliminarily set work shape by providing a work shape setting part which sets an arbitrary work shape and a work shape processing part which commands and processes the work shape in the normal/reverse direction. CONSTITUTION:Command data is generated in a work shape processing part 11 in accordance with the work shape set by a work shape setting part 10, and a speed command synchronized with manual handle pulses is generated in a manual handle control part 12. These shape command data and speed command are sent to a machine control part 3 to distribute interpolating pulses, thereby performing working into a prescribed shape with the manual operation similarly to the automatic operation. A processing part 11 generates command data corresponding to a working program; and if the manual handle feeding direction is changed on the way of a manual handle feeding command, the processing part 11 generates command data from the current position to the start point to control axes along the work shape with respect to the reverse feeding command.
